8 Claims. (Cl. Y(f8-49), A A

.v invention relates to ironing machines having cooperative; rolly andchest parts-and known Such a machine includes as elementary combinationof ironing parts, a heated metal chest having an ironing face, and apadded rollr bearing thereupon. The ironing face is of :generallycylindrical characteristics to fit the roll, butthe Achest `has a lipboth ahead andbehind thefroll by which the ircning'face is extendedtosupport `the Work'as the latter enters yand leaves respectively betweenchest` and'roll. The

'- roll is driven, to bear the work against the ironing face and tocause the work to progress thereover and thus accomplish the ironingoperation.

Such an ironing machine usually has more than onepair of cooperativeelements as described, but

" this inventionrelates primarily to that pairof roll and chest partsbetween which the work is first fed. `It has been found that insuch amachine, and particularly where there is a hem on the leading edge ofthe work, there is a decided tendency of the work to turn under androllback upon itself,`between the 1011 and chest parts of the ironer.Such malfunction is frequent when handkerchiefs andthe like, which arehemmed all around, are being ironed Aand especially4 when these havenarrow rolled hems. In many cases the work is damaged and in some caseeven the padding of -the ironing roll itself has been damaged. l

y It is the objectof this invention to prevent such malfunctioning, andfurther objects are to ac-` complish this by simple and inexpensivemeans. r The exact nature of this invention together with 'furtherobjects and advantages thereof will be apparent from `the followingdescription taken r in' connection-With the accompanying more or Ylessconventional drawing, wherein corresponding parts have correspondingreferencecharacters, and in which Figs. l and 2 are details in plan andtypical'seetional elevation of pertinent parts of an ironing machine inwhich an embodiment of the invention has been incorporated; Fig. 3 is aview corresponding to Fig. 2 but showing a preferredf form of theinvention; Figs. 4, 5 and 6 are details in sectional elevation, frontelevation and plan respectively; of another embodiment of the invention;and Fig. 7 is a sectional detail illustrating the characteristics of themalfunction which this invention is designed to overcome.

With reference now to the drawing and rst .to Fig. 7 thereof, l and 2represent the chest and rollrespectively of an ironing machine. The roll2 is driven as indicated bythe arrow and the Achest I has a lip part 3to which the work is fed by ymeans, of `a travellingbelt 4, therusualngers 5; extending from the belt `to assist in the feeding operation.The position ofthe leading edge of the Work as it contacts with thechest is indicated 'at a. As the work advances over the ironing face ofthe chest and contacts with the roll, its position is indicated by thedotted line b. At'this instant as indicated at b, the leading edgeonlyof thework may be bearing againstthe chest, and tends to stick upontheironing surface. The roll, however, engaging the work immediately backof its-leadingedge, forces the work between roll and lll? chest, causingthe Work to roll upon itself as indicated at c. As the work progressesthe'tendency 'of the chest to drag upon it, plusthe tendency of the rollto advance it, makes the work continue rolling about itsleading edge asat d.

With reference now to Figs. l and 2, the chest la and roll 2a arearranged and related as before, as arel the parts by whichthe work isfed Tonto the lip'of the chest, these parts including the feed belts 4aand ngers 5a. It will be appreciated that vthe chest la islhollow asyindicated, that it may be heated by steam conductedtherethrough; andthe roll 2a is driven asindicated by'the arrow, is caused to bearagainst the polished ironing surface ill of the chest, andisperipherally. padded, all as will be appreciated'by one familiarwiththe art. V f f According to this invention I provide a number ofmembers arranged inspaced relation and;` extending over the ironing faceofthe lip 3a, `in

the"directi'on oftravel of the work, up to andE` slightly under the roll2a..` These members 6 `are secured against travel with the work. Theymay be of sheetmetal, integral with a frame or backing part 'i which isturneddown over the edge of the li'p 3a, of the chest andthere'securedas by screws 8. By this simplearrangement the members 6 are of courseintegral with each other as l well as firmly securedwith the chest, therelation of the members 6 being that of teeth in a comb.

`'Ihe free ends of the members 6 extend but The resultis that` the Workvkwill have slight de` formations yextending in the direction of fits'travel, and will bestiffened against rrollingas described inconnectionzwith'liig. 7. Also, the leading edge ofthe work will nottouch the hotter ironing surface of the ironing 'chest so thatitstendency lto stick will be' materially decreased.

Consequently oncefthe work .touches the roll 2a itwill be moved by thelatter, from the members t 6, over the ironing surface I0. of the chestand onto the next chest lzfof the ironing machine.

`With reference now to the preferred modifica- A tion of Fig. vv3 thearrangement is as before except'f that the intermediate parts of themembersibjy areraised somewhat fromfthe lip' 3b of the chest by thesimple expedient of making thel frame part 1b with`V which 'the membersBbw-fare integral,

free extremities 9b `of the-members 621 slightly underliethe roll Zbasbeforeandhave feathered*r extremities. vAs compared with`the'arrangement Ycf Figs. 1 and`2, the arrangement offFigS differsY ineffect that the spaces between the members 6b'- are'deeper than before,so' that `the* entire leading edge of the Work is engagedfbyl the roll 2bbefore itpasses off' the'memb'ers. 6b and .engages the ironingsurfacelb.

upto the roll,2c`, where they terminate. graduallyk vas indicated inFigs. 4 and 6.

It will 'be apparent that so faras concerned, the effect of thearrangement offlr'igs. 4- 6 is substantially theisame as of that ofFigsnl and 2; the principal difference being that in thek former casethe deformation of thevwork' yis ac complished by means .integrali withvthe chest;
